SPECIFICATION forming part of Letters Patent No. 651,204, dated June 5, 1900.

Application filed April 27, 1899.

To all whom it may concern:

Be it known that we, WINFIELD S. PRYOR, EDWIN O. SHERWOOD, and OLIVER I-I. CLoYD, citizens of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Forges, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to furnaces for'heating metals, and particularly to that class known as forges.

The objects of the invention are, first, to

provide novel means for directing a steady supply of air through the products of combustion in a forge; second, to provide novel mechanism whereby the air-pressure may be increased or diminished to suit particular requirements, and, third, to so arrange the parts that they may be readilyassembled or disconnected and to provide means for removing any deposits of ashes or the like in the airpipe.

With the above and other objects in view the invention consists in the novel details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification,wherein like characters denote corresponding parts in the several views, and in which Figure l is a View in elevation of a forge with the invention applied. Fig. 2 is aview in elevation taken from one end. Fig. 3 is a sectional view of the air-chamber, draft-pipe, &c. Fig. 4 is plan view of the bottom of the air-chamber. Fig. 5 is a detail of one of the valves of the air-chamber.

In the drawings, 1 indicates the bowl of a portable forge, and 2 the legs for supporting the bowl. Brackets 3 are attached to the bowl and have angular extremities to which the boxes 4 of the crank-shaft 5 are bolted. The cylinders 6, of the air-pumps are attached to the curved bars 7, fixed between the legs at one end of the forge. Guide-rods 8 eX- tend from the cylinder-heads to the brackets 9. The apertured cross-heads 10 travel on the Serial No. 714,752. (No model.)

guide-rods and the piston-rods of the cylin ders are attached to the cross-heads. Pitmen 11. connect the crank-shaft and cross-heads for the purpose of operating the pistons (not shown) of the cylinder in opposite directions. A suitable fly-wheel 12 is rotated by the bevelgearing 13, and crank-handle 14 is provided for operating the crank-shaft.

Pipes 15 conduct the air from the pumpcylinders to the chamber 0, which is designed for the reception of the compressed air. The lower head of the chamber'is apertured and couplings e are attached on the outside surrounding the apertures. The valve d rests on the valve-seat of the coupling and is integral with a ring d, which is interposed between the coupling and the head of the chamber.

The pipe Z) extends horizontally and has a branch I) communicating with the interior of the chamber. The pipe 1) passes through the draft-pipe a and is provided with a number of apertures b in its wall on the upper side, said apertures being within the draft-pipe, so that the air passing through the apertures 19 under pressure will force sufficient air through the firegrate e to the fire-bed to support combustion. The force with which the air is supplied will be regulated by the operation of the pumps.

The pipe 6 is provided with a cap 6 which can be removed for blowing out thedust,

ashes, &c., which may have accumulated between the apertures b and the end.

The construction, operation, and advantages will, it is thought, be understood from the foregoing description, it being noted that the arrangement of the details for successfully carrying our invention into practice may be variously modified to meet particular requirements or circumstances, as will be obvious to those skilled in the art, without departing from the scope of the claims.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, isv 1. In a forge, an air-chamber, pumps in communication with the air-chamber, a firegrate, a draft-pipe, open at its lower end and stationed under the fire-grate, a horizontal pipe connected with the upper head of the chamber and passing through the draftpipe,

said horizontal pipe having apertures in its upper Wall within the draft-pipe, substantially as described.

2. In a forge, an air-chamber, air-pumps in communication with the air-chamber, couplings on the Outside of the lower head of the said air-chamber, Valves seated in the couplings, a fire-grate, a draft-pipe open at its lower end, stationed under the fire-grate, a horizontal pipe connected with the upper head of the air-chamber and passing through the draft-pipe, said horizontal pipe having apertures in its upper Wall Within the draft-pipe; and a cap on the end of the horizontal pipe, substantially as described.

In testimony whereof We afiix our signatures in the presenoeof two Witnesses.
